Since enum members can only be initialized with compile-time constants, the compiler will report a compile-time error if developers erroneously use assert_static where they should have used a traditional assert. Maybe putting "-lsz" in LIBS is not the right place, perhaps it needs to be in LDFLAGS or LDLIBS. Traditional assertions check assumptions made by developers at runtime.

This is annoying, especially if a company follows the "zero compiler warnings" paradigm. Recent Articles Headline Dr. Copying from repo to src path... https://bugs.debian.org/458129 Creating a simple Dock Cell that Fades In when Cursor Hover Over It How do I debug an emoticon-based URL?

But perhaps you are more interested in the number of significant bits of your data type? Missing \right ] splitting lists into sublists Will a void* always have the same representation as a char*? Printfing: Again, this is not about 'conversion' but about 'interpretation' of series of bits. assert_static(gWriteMode != WRITE_MODE_READ); // Wrong This expression cannot be evaluated at compile time and, hence, must be evaluated at runtime.

A couple of years ago, I needed to store structs in nonvolatile memory (NVM).

To get you up to speed, I've listed some more examples and use cases. Well, even though the optimization worked nicely, it is based on a fair amount of assumptions: S08 is a signed type.

If you are working on a C or embedded C++ project where templates and/or template specialization are not available, you might consider these implementations: The first approach takes advantage of the Maybe exit and restart.
